Conductive Fluoropolymers (TRC Series)

Contradictory Performance Of Conductivity And Cleanliness Achieved With The Special Technology.

We have developed a product imparted with electrical conductivity to fluoropolymer with high insulation properties, while maintaining the cleanliness and chemical resistance that are the characteristics of fluoropolymers.
Particularly for PCTFE resin that is our specialty, we have achieved to impart a stable conductivity to it for the first time in the world.
Our CNT fluoropolymer (TRC series) solves the problem with static electricity considered to be impossible to be solved so far.

What Is TRC (TOHO Resistivity Control) Series?

Features

  1. Stable Electrical Properties
    Stable electrical conductivity with little variation in volume resistivity is achieved by uniformly dispersing CNTs (carbon nanotubes) in fluoropolymer.
  2. Low Metal Elution
    The addition of a very small amount of CNT (1% or less) provides conductive performance and solves the problem of metal elution, which has been one of the issues with conventional conductive fluoropolymer materials.
    This series achieved a metal elution level equivalent to that of fluoropolymers without CNTs and thereby suit applications that require extremely high cleanliness.
  3. High Chemical Resistance
    This series maintains the chemical resistance that is one of the characteristics of fluoropolymers, and thereby can be used in harsh environments such as strong acids and strong alkalis.

Assumed Applications

Assumed Applications of TRC
  1. Driving parts such as rotating mechanisms and bending mechanisms
    Parts that are subject to frictional charging due to driving of gases and liquids
  2. Gas-liquid fluid parts
    Piping parts that become electrically charged unless the flow velocity is reduced, and nozzle parts that cannot uniformly apply liquid if the liquid becomes electrically charged
  3. Substitute for metals
    Parts that were conventionally coated with metal but need to be coated with resin to achieve higher cleanliness
